I have a ryobi weedeater model no.700R"ez" gas line was broke changed all fuel lines and primer bulb but i still have air in lines. it cranked up and would run full throttle for about one minute and die out cleaned carb. and changed all gaskets and still does the same thing. high screw is set at about 2 and low side is set at about 1.5. can anybody tell me what im doing wrong?

 

Hello sniper!

Are you sure you have the fuel lines connected to the right places? Sounds like maybe the ones on the primer are backwards.

 

no tryed that the other way it want hardley suck any gas at all i don't know what the deal is tryed replacing the lines again but the same thing

 

With the lines disconnected fromthe primer, place your finger over the primer holes and press the primer. The one that blows air out should go to the line that goes to the tank. The side that sucks air in should connect to the line going to the carb. If it doesn't want to prime that way, the carb is clogged.
